. EXPLOSIVE-ENGINEi To-a-ZLw/wm it may concern:

Lewis R. ONEILL, a citizen of the United States, residing at Des Moines,in thecounty of Polk and State of Iowa, have invented a certain new anduseful Explosive-Engine, of which the following is a specification. I

This invention-relates tocarbureters for explosive engines, a 3' 1' .Theobject of this invention is to provide a h simple, durable andinexpensive engine.

1 There is the usual air inlet, liquid fuel inlet and mixing chamber;the passage connecting these inlets with. the mixing chamber isprotitled with a valve for .each inletand means these valves :to moveoutside the passage in which they operate. I also provide a straightline reciprocating valve to cooperate withsaid valves.

The accompanying drawings illustrate the invention: w

7 Figure 1 is a perspective view .of the com plete engine.

Fig.2 is a vertical, central, secthe engine. Fig. 3 is alienlFargeddetail sectional view on the line'5-5, 1g, 2'. There is an engine base10, a crank shaft 4 i chamber 11, 13, containing a crank shaft 12;-

the engine cylinder 1.4 has exterior radiating rings 15; cylinder 14 hastwo ports 16 and .17 conneoted b'y passage 18. On the opposite 14'isexhaust port 19 in a slightly higher plane than port 16; immediately'belowjport 19 is an induction port 20 The piston" head 21 has acylindrical extenn ati'ts bottom, pitman 23 connects the p ston'head 21and crank shaft 12. In -t he'- part.22 'is a port 24 in position tocommunicate with port 17. On the top of the piston head 21 is adeflector 25 adjacent to. port 16 when piston head 21 is at its lowestThere is a spark producing'devi'ce 26 of ordinary construction connectedby conductor 27 with one pole of battery 28 conduc'tor 29 connects theopposite pole of battery 28'with'the-engine frame. -There are twoswitches'in said circuit, a manual switch,

and an automatic switch, consisting of the fixed contact 32 on an arm 31in position to a rotary contact fixed to the shaft 12. There is amufflerand air heater formed of' a rim 38 in position-to disks 37, each havingengage each other on the inner face of each Specification of LettersPatent. .Application filed-June 2, 1906.

eating with va 3) and a pipe 57 connects said extension with lene.

' mentof the piston is su Patented July 28, 1908;

. disk is a series of ann'ular'rims', like 39, 40, 41 v and 42. Aperforated pipe 42 at the center of the muffler connects withdischarging pipe 43 and pipe 44 connects exhaust port 19 with themuffler.

I have rovided' means for supplying gas to the cyl inder as'follows:Connected with the induction ort 20 is a pipe 46 communil ve casing 47the latter casing as a screw plug 48 su ortin a valve stem 5 PP b 49 andvalve 50 in position to close against a valve seatat the top of thecasing. A'spring 51-normally' holds-the valve against its-seat.Communicating withthe top of the casing above the valve is a pipe=52containing cut off valve 53 having on its stem crankdisk 54. At theupperend of pi e 52 is an elbow 55 opening adjacent'to t e Inufiler. Onone side of valve casing 47 is an extension-56 (Fig.

7 5 tank 58 containing a liquid fuel,'such as gaso- Extension 56 isprovided with a small passage 59 leading into a larger openingwhichconnects with the interior of valve. casing 47 at'a oint inline with thevalve 0 seat therein. ointed. screw 60 is mounted" in this opening andits end so arranged that when ad'usted to one position, it wil out Ohthe supply of gasolene, and when adjusted to other positions will reulate and control the quant ty of gasolene admitted. Mounted on screw 60is crank disk 61 connected by rod 62 with crank disk 54 so that thesedisks and the valves they control are adjusted simultaneously or movesynchronously. Inpractical use, assuming that screw 60 and valve 53areboth set to admit gas'olene and air in roper relative r'oportions,and assuming that suction ro need by inovecient to lowervalve 50 thengasolene and air in roper proportions will be drawn into the c amber atthe bottom of the cylinder.

If it is desired to introduce a greater quantity of gasolene and'airthen the rod 62 is manipulated to open valve 53 wider, and this willresultin operating screw 60 to admit proportionally a larger quantity ofgasolene, and

m this way the proper proportion between air and gasolene is alwaysmaintained regardless of the volume of both requiredfor the engine.Mounted on shaft 12 is fly wheel 7 63 having fan blade spokes 64 toforce air over the cylinder to cool i It is to benoticed that valve 50has a I f straight line movement across the opening controlled by therotating'valve stem 60 and tends to keep the mouth of the passagescraped cle an.

What I claim and desire to secure by Letters Patent is: I

1. In a carbureter the combination of a source of liquid fuel, an airinlet, a mixin chamber, and means for controlling the passage of air andfuel consisting of an air valve opened and closed by a rotary movement,a fuel valve opened and closed by a rotary movement, a valve controllingthe combined fuel and air supply, said valve reciprocating in a straightline across the fuel supply inlet, and a mechanical connection betweenthe two first named valves whereby the adjustment of one produces acorresponding adjustment of the other.

2. In a-carbureter the combination of a liquid fuel inlet, an air inlet,a mixing cham her, and means for controlling the passage of combined airand fuel, consisting'of an air valve opened and closed by a rotarymovement, a fuelvalve' opened and closed by a rotary movement, aseparate valve reciprocatin in 'a straight lineacross the fuel supplyinlet, and means whereby the air valve and the fuel valve are caused tomove synchro-- nouslyt.1 r
